Maximum page display height! A single combo Navbar(withAddr-SearchCombo)/Titlebar/Addonbar/Status&Link-display/Progressbar in 1/4 the usual height. Optional vertical toolbar & tabs along the left edge
AiOS lets you open various windows as sidebar panels, and quickly switch between them. So it put an end to the window chaos! In addition to bookmarks and history it opens dialogues such as downloads, add-ons and more in the sidebar.
Collector's Note I've used this mainly for its toolbar, as a heavyweight alternative to Vertical Toolbar.
NoSquint allows you to adjust the text-only and full-page (both text and images) zoom levels as well as color settings both globally (for all sites) and per site.
Collector's Note Optional: a more sophisticated alternative to Zoom Page: Often you can fit more on the page by shrinking it (zooming out). Even more so with this add-on because you can change the text to any size while you still have any overall page zoom. Firefox natively (and other add-ons) only allow you to have a custom overall page zoom or a custom text-only zoom, but not both simultaneously. See my review https://addons.mozilla.org/firefox/addon/nosquint/reviews/368821/
Show tabs like a tree.
Collector's Note Suggested: if you have enough screen width (e.g. a widescreen) you can use this to make a vertical tab bar along the left edge of the screen. You can also drag almost anything else onto the tab bar -- especially items that are wider than a single button. I just keep a sole navigation bar along the top of the screen for the address bar, althouth you *could* even put the address bar as the first item on this vertical tab bar, especially if you let the tab bar "auto-expand" in this extension's settings. Having a vertical tab bar also allows you to see dozen[s] of tab titles at once without scrolling them. You'll probably want some more "tab management" add-ons if you use so many tabs -- I like Tab Utilities by ithinc but I have to set it *also* to put the tab bar on the left or else it can become incompatible with Tree Style Tab by making the tabs themselves vertical and narrow side-by-side in the vertical tab bar.. A vertical tab bar may not be so space-efficient if you like to put several browser windows next to one another, since each will have its own vertical tab bar taking up some screen width. In this case I suggest unticking/clearing Firefox's Options-->Tabs-->Always show the tab bar, so any windows having a single tab won't show that tab bar at all (you can always show it by adding a second tab with Control-T). Alternatively, setting "auto-expand" in Tree Style Tab could help (I like auto-expand better than auto-hide because it gives you a bigger area that you can move the cursor into to activate it). I really like the "tree" aspect of this addon, which means when you open a link in a new tab the new tab appears indented under the current tab -- it's easier to understand this when you try it than when I try to explain it.
Status bar widgets and progress indicators for Firefox 4+
Collector's Note ! One of the 5 Core Add-ons of this Collection: This extension lets you display the Link and/or Status text in the Address Bar (right-hand side). This avoids the coverup of content area when they pop up at the bottom of the page normally. When the page is done loading and you aren't hovering over a link, the entire address bar is again available to display the URL and what ever else it's being used for by the other add-ons. Alternatively you can move the Link or Status text back into the Add-On bar where it used to be (hence calling it the Status Bar); then you could use the url-addon-bar extension to move all of it together into the address bar, but I find it works better to let Status-4-Evar put the things directly into the address bar itself. Also can add a background (zero footprint) page load progress bar to the address bar, Safari-style. BTW, the functionality of this add-on is built into the Pale Moon browser, a Firefox variant.
Full featured zoom manager with independent page and image zoom modes. Choose from four zoom modes: Default Zoom, Fit-To-Width, Default Zoom + Site Specific or Fit-To-Width + Site Specific. Button style and zoom levels are fully configurable.
Collector's Note Suggested: Often you can fit more on the page by shrinking it (zooming out). Slightly simpler than NoSquint; also has a nice set of alternative zoom combo buttons for toolbar.
Integrates location bar and search bar into one. Shows search and url suggestions. Quickly switch search engine using search keywords. Provides different auto-complete popup styles for compact displays.
Collector's Note ! One of the 5 Core Add-ons of this Collection: This extension eliminates the need for the separate search bar by integrating it into the address bar. Firefox already does this only to a very limited extent -- with this extension you get the full search bar functionality such as autocomplete suggestions from the search engine etc. The only downside I've noticed is that you can't easily retreive the search terms you just entered within this bar. You have to do so in the searchbox within the search engine's own page.
Make your bookmarks bar better. Roomy Bookmarks Toolbar can: hide bookmarks/folders name(dock like), multirow, autohide and many another features(more than 20).
Customize your bookmarks bar using one add-on.
Collector's Note Optional: I don't seem to need this add-on anymore, although I'm not sure what changed. Now I just Customize and drag my "Bookmarks" object from my Bookmarks Bar to my Vertical Toolbar and I get icons-only there without using Roomy Bookmarks Toolbar. BTW, I like to put bookmarklets (google it) on my bookmarks bar, and I now use Bookmark Favicon Changer to assign icons to these so I can distinguish them on my toolbar without text labels. Here are my older notes: "This add-on can show just an icon for each bookmark in the bookmarks toolbar (can show the name when you hover over, though in a strange, non-tooltip way). I use it and I move my bookmarks from my Bookmarks Bar into my vertical Tab Bar (or elsewhere) and have Roomy wrap them into multiple lines (using Fixed Height). If you're going to show icons-only for bookmarks, you might want to be able to set the missing/generic favicons for sites that don't have them -- for this you could use Bookmark Favicon Changer (or Favicon Picker 2 which I haven't tried); or what I do is use IdentFavicon to automatically give each faviconless site a favicon before I even bookmark the site."
"Maximize your screen space by controlling the presence of Firefox window Title-bar (Caption) & borders!", to be like Chrome Browser. - Hide FF's caption with 'smart' options, *optional* custom caption & resizers. - Works with ChromiFox-like themes.
Collector's Note For non-Windows systems this replaces 2 of the 5 Core Add-ons of this Collection (Personal Titlebar and its necessitated Compact Menu 2). For Windows it's an optional (more complex but capable) alternative. This add-on takes the opposite approach to Personal Titlebar by hiding the titlebar but putting the "Firefox" app. main home button (optionally shrunken as narrow as "F" as an alternative to Movable Firefox Button or UI Fixer) and minimize/maximize/close window button trio onto the navigation bar (the toolbar containing the address bar). You can also have it show a "floating" main menu and web page title when you hover on the Firefox button. You can also set a smaller toolbar and tab bar height and adjust "top edge margin position" to make it as slim as you want up there. On non-Windows platforms it can replace the native minimize/restore/close with its own smaller, auto-hiding version. The problem with hiding the titlebar is there's nothing to grab and drag, so it provides special drag areas that you can put there, and it also makes the unused area of the tab bar click-and-dragable.
A very compact & highly customizable theme that minimizes space consumed by menu & tool bars without hurting the overall usability. Supports Windows, Mac & Linux.
Collector's Note Optional: If you want to squeeze the bar, button, and font sizes themselves, this Theme will do it. Most of the other extensions in the present collection should work with or without this Theme.
This add-on allows one to customize the theme "Classic Compact". Options include: 10 different toolbar button sets; turning off gradient backgrounds; OS scrollbars; dark system color support; merging menu bar into one menu button; etc.
Collector's Note ! You could use its Display Tabs In Titlebar: Always as an alternative to core add-on Personal Titlebar (or Hide Caption Titlebar Plus). Don't forget to also set Firefox's "Tabs on Top" option (right-click toolbar blank area). The extension Tabs Always in Titlebar provides that same single functionality but leaves an empty space if you use something like Movable Firefox Button to move this button off the tab bar. Has lots of other options. Intended for use with the Classic Compact theme, but needn't be.
Adds a vertical toolbar at the edge of the window.
Collector's Note Suggested: if you want to move your buttons to a vertical toolbar along the left edge of your screen. You can even drag "Open a new tab" and "List all tabs" from the end of the tab bar onto here. You won't want to put any "wide" items on the vertical bar though. With this, you might need *only* the tab bar along the top, if you drag the address bar and everything else onto the tab bar.
Add a compact menu button to the navigation toolbar, and hide the menu bar.
Collector's Note [Update: this addon breaks the ability to edit a bookmark while adding it (blocks the pop-up dialog)! See my review of it on 24 Jan 2013.] ! One of the 5 Core Add-ons of this Collection (or at least when using Personal Titlebar which is Windows-only): You'll probably need this in order to restore access to the legacy menus if you use Personal Titlebar and move those menus off of the Menu Bar in order not to display them full-time. Compact Menu 2 puts the legacy menus as submenus of a new "Menu" item within the Firefox main app button's own dropdown. The usual keyboard shortcuts will work (such as Alt+T for Tools menu). BTW, this wouldn't be necessary if Firefox itself would (please) make all the "legacy" menu commands available through the single main Firefox app button instead of having to use a hodge-podge of both menu systems (there are some other add-ons that try to add back some of the other functions from Tools and other legacy menus into the main firefox app button).
Move Firefox Button to anywhere you want, and make it also available in Full Screen mode, or when Menu Bar is showing.
Collector's Note Optional: Another way to drag the firefox button onto any toolbar. See UI Fixer which I use instead of this this add-on simply because it can also make other things movable (like the "immovable" add-on bar items).
